Question

Like in animals, in plants also, the embryo develops in a phased manner that happens in sequential order. Below is a list of various stages of embryogenesis in a model dicot plant (Capsella bursa-pastoris). Arrange them sequentially in the proper order of development.
(A) Globular stage
(B) Torpedo stage
(C) Heart stage
(D) Pro-embryo stage

• A. (D), (A), (C), (B).
• B. (D), (B), (C), (A).
• C. (B), (A), (D), (C).
• D. (C), (B), (D), (A).

Hint:

To remember the stages of dicot embryogenesis, think of their physical shapes progressing from simple to complex:
Pro-embryo (D) $\rightarrow$ Round Ball (Globular, A) $\rightarrow$ Heart-shaped (C) $\rightarrow$ Elongated (Torpedo, B).
